I plan on using Cannon in D for the bridal entrance in my wedding. Does anyone know any similar pieces?

I'm looking for another soft piece for the processional, haven't really been able to find anything I really like. I liked Pachelbel's Serenade. I can't find sheet music to it though. I found it on itunes by the artist "Avalon" ... not sure if it's quite right... because I can't find it. I'm not very knowledgeable on clical music, and I'd LOVE some help, Thanks!!
